Can anyone tell me why sphingomyelin is one of the main phospholipid components of animal plasma membranes but is not found in the membranes of mitochondria or chloroplasts.

I understand that the lipid content of mitochondria and chloroplasts is much lower than the lipid content of the plasma membrane but I can't find a reason as to why the lipid that is present does not include sphingomyelin.

Is there a functional difference between sphingomyelin and other phospholipids (ie phosphoglycerides)??


Any help would be appreciated, thanks!

With the recent news that there might have recently been water on Mars, people are wondering if that means there is/has been life there, but why does water have to exist for life to exist. Couldn't life on another planet have developed in a manner much different from our own?

If we consider to do some repetitive stuff like typping the same keystroke, at some time we are going to fail. I think that is due to some information attached to us, which if we discovered, and altered, we are going to limit those imperfections. Doing this, will also allows us to perform better in sport, because we have some restrictions in speed, jumps, etc.Besides, have you heard that under extraordinay circumtances, we can do something (jump higher, run faster) due the the adrenaline? So please, consider this information to be useful for your answer.
